<DIV>I have a Titan, OS 1.60, Mueller header, Greve pipe, Ironbay regulator
before the needle valve, OS #8 plug, running a 17x13 with 15%.
Tank is monted over the CG. Hyde mount. As near as I can measure
around the header, I am at the length that Piedmont recommends for these pipes
on their site. Good power at full throttle, but midrange stinks, wanting
to load up at 3/4 throttle, and not transition to full throttle. Also,
the mixture changes in the air, upright to inverted, going rich
inverted. I have the regulator mounted horizontally about 1.5 inches
from the needle, do I need to mount it fore-aft like a Cline? Do you
think I need to extend the length of the pipe? Any carb adjustment
tricks? I'm new to pipes, so any info will help.</DIV>
<DIV> </DIV>
<DIV>BTW, the original pressure check valve went bad before I even got
to fly it. I got a check valve (Foremost) from my local hobby
shop that seems to work, developing pressure and holding it well.
Have others had problems with the Ironbay valves?</DIV>

<DIV>Thanks.</DIV>
